DONT WORRY >>IT IS NOTHING BUT 2x^2=x+2...or...2x^2-x-2=0
NOW SEE THE FOLLOWING EXAMPLE AND DO
√9x^2=x+6
3x^2-x-6=0
use the formula and solve
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%281+%2B-+sqrt%28+%28-1%29%5E2-4%2A3%2A%28-6%29+%29%29%2F%282%2A3%29+
x+=+%281+%2B-+sqrt73%29%2F6+
